ST. LOUIS (KSDK) - On Tuesday afternoon, family and friends walked to the exact spot where LeShaun Holmes and Lonnell Dortch were gunned down exactly one year ago.

"It's been really rough," said Lucretia Mensey, Holmes' sister. "My mom couldn't even make it to the vigil today because she couldn't bear to be at the scene where her son was last alive at."

"It's just been rough, especially the fact that justice hasn't been served yet," said Marquitra Dortch, Lonnell Dortch's niece.

Holmes and Dortch were in a car on Annetta Street in the city's north side when they were shot. Neither was from that part of town. Marquitra Dortch says they still don't know why they were there.

Police have made no arrests, but Marquitra is sure someone knows what happened.

"Somebody out here knows something, but they may just be afraid to come forward. Maybe they fear someone will have some sort of retaliation towards them or something like that. But we'll never know until they come forward," she said.

"I think society has been desensitized by movies, video games, by music in some cases. We need to do a better job of letting people know that that's what their responsibility is in society," St. Louis Metropolitan Police Chief Sam Dotson said.

Chief Dotson was there for the vigil. He says without the public's help, they can't solve crimes like this one.

"That person is still in society and out in public, and still putting people at risk," he said. "That's why we need the citizens' help in contacting CrimeStoppers to tell us information about this crime because if they offended once there's always a chance they could offend again and we need to put a stop to that."

So they don't put another family through this.

Anyone with information on this murder, or any other murder, is urged to call CrimeStoppers at 866-371-TIPS.
